Give Your Herd the Strong Start They Deserve
Calf scour (diarrhea) remains one of the most critical challenges during calving season, accounting for up to 40% of calf deaths in the first six weeks of life.
Left unchecked, it leads to dehydration, malnutrition, and stunted growth, costing farmers over €53 per case in treatment alone.
Tonisity Rum-X is the solution. It is a highly palatable isotonic protein solution designed to support hydration and intestinal function in calves, lambs, and goat kids. By supporting intestinal development, it helps support nutrient uptake, hydration and early-life performance.
